MEANS FQRTREATING CERAMIC MTXTURES..

` Application led- March, 1926. Serial No. 92,788.

- The present invention relates to means for Upstanding portions 10 provide guideways treating ceramic mixtures.

More particularly the present invention relates'to lmproved means for carrying out the processdescri'bed in United States Let-v ters Patent No. 1,559,652, granted November 3, 1925, to the present applicant.` According to said process, a ceramic mixture'is subject-- ed to reduced air pressure, commonly. referred to as a vacuum, and the vacuum is suddenly broken, whereby to effect the elimii nation of gases Yfrom said mass.

An Object of the present invention 1s to provide an improved means for suddenly opening a vessel whereby to admit air there.

to with suddenness and in large'quantities..

A further object is to provideian 1mproved `vessel adapted to contain a mass Aof with means for evacuating the air therefrom and with mea-ns for` suddenlyl breaking the vacuum within said vessel. Y

Further lobjects will appear scription proceeds.

Referring to the .drawings- Figure 1 is a view, in side elevation of one embodiment of .the present invention; Figure 2 is a sectional view, .on an enas the de# Y larged scale, of part of the structure shown in Figure 1, which view shows a ynovel type of air inlet valve and Acontrol means therefor, said sectional view being .taken along,` the plane indica-ted by thek arrowsy 2,-2 :foff]5`ig ure 3;

`Figure 3. is an end View -of 'thestructure shown in Figuresl and 2;

which is connected .to the vacuum plum-p3, the manually operable .valve 4 being provided to control the connection'hetween 'said v pipe V3 and: said .g cylinder 1.

A pressure gauge 5 may be provided for indicating the pressure within said cylinder-'1.

The cylinder 1 is `provided on its -`upper portion with an aperture, indicated by the numeral 6, above which aperture is mounted the` valve seat 7, comprising a plurality of bridges 8--8 spaced apart by spaces9-9.

re 4y is asectional view taken along.

ingpreferably a little wider than the apertures.v When'the valve 11 is in one selectable position, the bridge; members 1212 thereof will bridge the apertures 9&9 of the'valve seat to close the cylinder 1 from accessto the atmosphere.A When the valve 11 is inane, other selectable position, thatv is-the po#l sition indicated in Figure 2, the'apertures 13.-13 of said Avalve 11 willi coincide with the apertures 9 9 of theva'lve seat 7 and ready access is had between the interior of the cylinder 1- andthe outside atmosphere.

For controlling said valve'll` in order .that

v said valve may open with a snap action', a

spring Operated device is provided, which is' indicated as a whole by thenumeral 14. Said controlling device 14 comprises a. `housing 15, which may be mounted inianyfpre-v as, for example, upon the guideways 10,'be'- ing secured by means f of screws 15a-15'?. Saidl housing hasY mounted therein the plunger 16, .which plunger is connected vatv oneof its'fextremitieslto .the bracket 17, 'con-` nected to the valve 11 as, ,forexample .by means .of cap screws, oneeof whicliis indicated Vbyy t-he numeral -17 a.'

Y

Both end walls of thefhousing 15 are preferably removable, the end wall 23 compris- T ing one abutment for the spring 2O and the other end wall 24pproviding pivotal mounting means for the operating lever for controlling said plunger 16 and the detent for A controlling said plunger, n-hiclrparts will vlo now be brieiiy described. Said end wall`24 is provided with the bracket 25, having piv-f otally mounted thereonv the operating lever 26, which operating lever is adapted to abut against the. extremity ot the` plunger 16; Counterclockwise movement oi said lever 26 i will result in the movement toward the left Said shoulder 29 is adapted to be eiir,a'getl V by a gravity responsive detent -30 mounted to-reci-p'rocate within the bracket 31. Saidv detent 30 is connected by means ofl th-e'link 32 with the yweighted lever`33.

It will be clear that when the lever 26. Vis

moved ina countcrclockwise direction the.

" aluneer 16 rwill be moved to thepl-ett compressing the spring 2O and movingtlie valve 11`toward the lett. lVlienthe bridge vmembers 12-12 of the valve 11 are in position to cover the apertures 9 9 of' the valve seat' 7, theshoulder 29 ot the. plunger 16V will bev in position to be engaged by the detent 30,

whereby said detent will hold said parts in said .position to cutoff communication. from the interionof'the vessel 1I to the outside atmosphere.'r

tov the vessel 1, the lever 33 may be' lifted wherebyV to tree the detent30 from theY shoulder. 29, after which .the spring 20-will :move the plunger 16 and valve=12 suddenly` f to the right to the position shown in Figure 'said valve 2, withfthe right-handend of abutting against the plate 22.v

v-fkccorfdingr tothe modification lshown. in.V ,Figure "5, a'rotary-'valve is provided which maybe mounted upon a kwall of the vesselil.r

The `modification shown in Figure 5 includes the rotary valve 34, having thev bridging members 35-35, which are lseparated bythe v apertures 36436..v Said bridging members 35 are adapted to close apertures in the wall Yoi the vessel 1 whensaid valve is in one selectable position, and to permit access through said aperturesfwhen -saidvalve is in Y A tension-v springf37 biases said rotary, valve 34m a! anothery selectable position? counterclockwise direction, themovement of said valve being limited by reason of the entation of said valve 34 in a clockwise direc tion. When the valve is in the position indicated by thedotted lines 41, access is cut oit' between the outside atmosphere and the interiorrot1 the cylinder 1. In order to hold the rotary valve 34 in the position to close access to the interior of the cylinder 1, a shoulder 42 is provided, adaptedv to be engaged by a detent 43 which is adapted to reciprocate. in a bracket 44. A`weighted lever 45 is provided for"V biasing said detent 43 toits lowermost 4position and said detent 43 when desired. Y.

It willbe clear that when the structure shown lin Figure 5 is being used, the operator may close access to the cylinder 1 by'grasping4 the handle 40 andV movingthe rotaryV for lifting the outside to the .interior of said cylinderl.

At this time the stop 42-will beA in position to be engaged by the detent 43 and said rotary valve'will be held in closing position by saidfdetent 43. VVhen it is desi'red'tosudl denly admit air'to thevessel l, the lever '45V will be raised, whereby the'detent `43 is treed from the stop ment to a position wherein ythe stop38 "abuts l Y l' against thebracket 39, in which positionv kac- VVhen it isdesired to admit air suddenly vThough-` two` embodiments' ot the presentv invention have been described in detail, Vit
